Re: [Cppunit-devel] Subclassing Exception class for better test failure report

[Michael A. <ch...@mu...>]

Just a small point - I would like to be able to use CppUnit in Unicode =
projects, so I think it needs some generic string class which chances =
dependent on using Unicode or not. It could be a simple typedef to =
std::string or std::wstring.
